GridMapper v1.0

GridMapper is an application for Windows that allows you to rapidly develop dungeon and building complexes.
You start with a filled-in underground map, and from the first click you're clearing spaces for dungeon
rooms, corridors, etc. Additional options under "Tools" allow you to easily place doors, stairs, and walls.
Save, open, print, resize, and copy your map to other image-manipulation software. It's easy!
